Take a look at VictoriaMetrics. It supports OHLC function (rollup_candlestick) via MetticsQL [1], which is backwards compatible with PromQL - query language used in Prometheus. PromQL is optimized for typical queries over time series data [2].
VictoriaMetrics works out of the box without the need to set up third-party systems or wroting complex configs. It is also very fast for both data ingestion and querying [3], [4].
